When an object is moving with uniform circular motion, the centripetal acceleration of the object d. is directed toward the center of motion.
It would take 5.0 s for a racehorse to accelerate from rest to a speed of 15 m/s with an acceleration of 3.0 m/s.
Take 15 / 3.0 to get your answer of D. 5.0 s
Hope that helps u out!
Answer:
- 1600 mm
- 80 cm
- 0.109 kg
- 0.0056 kg
- 0.075 L
- 1.65 cm
Explanation:
The relevant conversion factors are ...
1 m = 100 cm
1 cm = 10 mm
1 kg = 1000 g
1 L = 1000 mL
These are based on the meanings of the SI prefixes:
centi- = 1/100
milli- = 1/1000
kilo- = 1000
__
2000 g = 2 kg --- given
14000m = 14 km --- given
1600 mm = 160 cm
0.8 m = 80 cm
109 g = 0.109 kg
0.0056 kg = 5.6 g
0.075 L = 75 mL
16.5mm = 1.65 cm
